Wavelength-Division Multiplex Systems TRIZ Cases
- DWDM Transponder Auto-Tuning Through Colored Passive Multiplexers
Sequential wavelength probing with identifier modulation lets a DWDM transponder self-tune to colored passive multiplexer ports without manual setup.
- External Pump Light Source With Mode Conversion for Optical Amplifiers
Multi-mode pump light is split into single-mode channels outside the amplifier, easing maintenance while supporting shared high-power optical amplification.
- Optical Fiber Amplifier Control Using Node ID Verification
Node identifier checks over the optical supervisory channel prevent wrong amplifier activation after fiber repair and avoid WDM traffic black holes.
